A person can also increase their vitamin D intake through certain foods or supplements. (1)

The sun vitamin is very important for maintaining healthy bones and teeth and can prevent many diseases such as rickets and osteoporosis. Even though vitamin D is presented as a vitamin, it is called a hormone precursor (calcitriol).

The further course of the text will deal with the importance for humans for health, symptoms and clinical pictures of a vitamin D deficiency, a possible substitution, possible combinations and the recommended daily dose, which forms there are for intake.

The definition of vitamin D

As mentioned above, vitamin D is a pre-hormone called calcitriol and is very important for bone health. It can only be produced with the help of sunlight. The collective term vitamin D includes several fat-soluble compounds.

This also includes vitamin D3, also known as colecalciferol. There is also vitamin D2, which is also called ergocalciferol. (2) This is converted in the body into the more effective form of vitamin D3. A deficiency can lead to softening of the bones (rickets), especially in children.

We have vitamin D3 drops from Zade Vital in our range, which will fill your vitamin D stores and provide you with vitality and strength. You can access the product here and buy it directly from the website.

The role of vitamin D in health

Vitamin D strengthens the bones and has an influence on muscle strength. Vitamin D is also said to reduce the risk of some diseases and may even minimize the risk of some cancers. It supports the immune system, brain and nervous system. According to studies, it helps against hair loss, obesity and depression and plays a key role in bone mineralization.

The tasks of vitamin D are in particular the strengthening of the immune system such as the defense against pathogens and the inhibition of excessive immune reactions. (3) It is considered an immune system booster in chronic and infectious diseases.

The 4 health benefits of vitamin D

[blog-product slug="zade-vital-vitamin-d3-1000-iu"]

1. Promises healthy bones by regulating calcium and phosphorus.
2. Reduced risk of flu
3. Healthy toddlers and infants
4. healthy pregnancy

In the following we will go into the individual points in detail.

1. Healthy bones

Vitamin D plays an important role. It is source in regulating calcium and maintaining blood phosphorus levels. These factors are critical to maintaining healthy bones.
Humans need vitamin D so the gut can stimulate and absorb calcium and reclaim calcium that the kidneys would otherwise excrete.

Vitamin D deficiency in children can lead to rickets, which results in a severely bow-legged appearance due to softening of the bones.
Similarly, vitamin D deficiency in adults manifests as osteomalacia. That means the softening of the bones. Osteomalacia leads to low bone density and muscle weakness.

2. Reduced risk of flu

A 2018 review source on the existing research suggested that some studies had found a protective effect of vitamin D against the influenza virus.

3. Healthy toddlers and infants

Vitamin D deficiency is linked to high blood pressure in children. A 2018 study found a possible link between low vitamin D levels and stiffness in children's artery walls.
The American Academy of Allergy Asthma and Immunology (AAAAI) notes that there is evidence of an association between low vitamin D exposure and an increased risk of allergic sensitization.

An example of this is that children who live closer to the equator have a lower rate of hospitalizations for allergies as well as fewer epinephrine auto-injector prescriptions. You also have a lower chance of having a peanut allergy.

The AAAAI also highlights an Australian study on egg consumption. Eggs are a common early source of vitamin D. The children who started eating eggs at 6 months were more likely to develop food allergies than children who started between 4-6 months.

In addition, vitamin D can increase the anti-inflammatory effect of glucocorticoids. This benefit makes it potentially useful as an adjunctive therapy for people with steroid-resistant asthma.

4. Healthy pregnancy

A 2019 review suggests that pregnant women who are deficient in vitamin D are at greater risk of developing preeclampsia and having a preterm birth.

Doctors also link poor vitamin D status to gestational diabetes and bacterial vaginosis in pregnant women.

It's also important to note that in a 2013 study, researchers linked high levels of vitamin D during pregnancy to an increased risk of food allergies in the child in the first 2 years of life. (4)

The causes and symptoms of vitamin D deficiency

If the body lacks vitamin D over a long period of time and clinically relevant symptoms occur, this is referred to as a deficiency. In this case, extreme deficiency symptoms would be rickets or osteomalacia.

In addition, there is an increased susceptibility to infection and reduced muscle strength. A deficiency can come from low sun exposure, which is particularly the case in the winter months. Germany lies between the 47th and 55th degree of latitude, so the intensity and duration of sufficient radiation decreases here and vitamin D formation depends on the season.

The symptoms of a vitamin D deficiency are as follows:

• Susceptibility to infection and frequent illness
• fatigue
• Bone and back pain in adults
• thyroid problems
• hair loss
• Muscle aches
• Impaired wound healing
• back pain, knee pain
• Decreased muscle strength, muscle pain and cramps
• Brittle nails and trouble sleeping
• Bone fractures due to bone loss (osteoporosis)
• mood swings and depression
• Overactive parathyroid gland
• Decreased height (in children) (5)

Bone and back pain in adults

Vitamin D also plays an important role in regulating calcium and maintaining blood phosphorus levels. Humans need vitamin D so that the intestines can absorb calcium, otherwise the kidneys would excrete it.

The deficiency symptoms in adults are often bone and back pain. Over time, this leads to bone loss and deformity and, in the long term, to osteoporosis. The internal "thinning" of the bone is accompanied by demineralization and often leads to pain.

Thyroid problems due to vitamin D deficiency

Thyroid diseases such as Hashimoto's are often associated with a vitamin D deficiency. In this case, taking vitamin D can lead to an improvement in the disease. Antibodies have been found to drop after taking vitamin D.

In the case of a thyroid disease, the need for vitamin D is increased, less vitamin D is produced in the body and autoimmune diseases prevent sufficient production due to a receptor disorder. According to a study in 2015, Hashimoto patients were able to reduce their antibody levels by an average of 20 percent with a vitamin D intake of up to 4,000 IU daily for 4 months.

hair loss

The symptom that often occurs with a vitamin D deficiency is hair loss.

Of course, there can be many other reasons for hair loss, but a vitamin D deficiency is a common reason why hair falls out more often, especially in winter.

The recommended daily dose is therefore:

• For infants 0-12 months: 400 IU (10 mcg).

• In children 1-18 years: 600 IU (15 mcg).
• In adults up to 70 years: 600 IU (15 mcg)
• For adults over 70 years: 800 IU (20 mcg)
• Pregnant or lactating women: 600 IU (15 mcg).
